Improvement in carbureters



PATENT @Enron JOSHUA GRAY, OF BOSTON, MASSACHUSETTS.

IMPRVEM ENT IN CARBURE'TERS.

Specification forming part of Lette rs Patent No. 147,256, dated February l0, 1874 application filed January 10, 1874.

To all whom 'it may concern Be it known that I, JOSHUA GRAY, of Boston, in the county of' Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Oarbureters, of' which the following is a specification:

The object of this invention is to take and use the carbureted gas direct from the chamber or gas-holder as fast as the gases are carbureted, and to prevent the gas from separating from the vapor of the oil. The gas in the machines, when taken from a tank or large space, will separate. The hydrocarbon olzvapor from the oil will settle to the bottom, as it weighs four ounces to the cubic foot, and the coal-gas, being lighter than air and not having a circulation, will, by its lightness, rise to the top, and the vapor settle to t-he bottom and condense, as the vapor will not rise but about sev en inches, unless it has a current to keep it in motion. For instance, if' you make iifty light machines of the Dayton or other pattern, and fan the gas down the tube and over the oil, thence into a large tank or space above the dcfiector, and light only a part ofl the burners, there will not bc current enough to keep the gases in circulation or completely carburet the gases; consequently the coalgas will rise to the top, and the vapor or hydrocarbon will settle to the bottom and condense,. and nearly as much coal-gas will be burned as without the carburetor.

My invention consists ofl an outer tank or vessel, which is partially filled wit-h oil or gasoline, and provided inside with an adjustable disk or float, the upper chamber of which forms a gas-holder, provided with an inlet and an outlet pipe, which are made flexible by means of metal joints, which permit such gas-holder to rise and fall within the tank as the volume oil oil or gasoline is increased or diminished within the same, being permitted to rise up when the oil is flowing in until a projection on the top of' the gas-holder comes in contact with a valve and closes the same, so as to prevent a iiow of oil or gasoline into the reservoir sufficient to check the inward passage oil gas, and permitted to fall gradually as the oil or gasoline is taken up and consumed after mingling with the gas and passing out through outlet-pipe to the burner in the f'orm of' carbureted gas.

Figure 1 is a longitudinal section of a cara bureter constructed according to my invention. F10'. 2 is a similar view, showing a modification of the disk. Fig. 3 is a plan view of the under side of the disk and gas-holder. Fig. 4 is a similar view of the modification shown in Fig. 2. j

A is the reservoir for holding the oil or gasoline, which is introduced through the pipe N, upon the top of the same. S is a valve, which is closed by the inward flow of oil raising thevdisk B, when the projection l? strikes valve S and closes it against the lower end of pipe l.

rFhe common coal-gas, being let in through inlet It, passes through the iiexible pipe G G inside the disk B, where it comes in contact with the oil or gasoline, as shown by horizontal dotted lines;` passing over the same, it absorbs or commingles the vapor or gaseous portion arising from the same; then it passes, through the small openings F F F, into the chamber or gas-holder O, and is conducted from said gasholder or chamber through the flexible pipe H, and out through the pipe K to the burners, where it is consumed in the form of carbureted gas.

rlhe scroll E E E, Fig. 3, shows a means of conducting a small flow of gas over a larger surface of' oil to be carbnreted than in the f'ormer method.

It will be understood that the flexible pipes G G and H H are to be made of metal with oints, so as to allow the free rise and fall ofthe disk and gas-holdcr inside of the reservoir A.

It' desirable, the gas-inlet pipe may be omitted, and the gas allowed to pass directly into I the chamber above the disk, and then through an aperture in or about the center of said disk, from whence it escapes by flexible tube H, and thus comes in contact with the carburetin g fluid beneath, and rising into gas-chamber O, thereby consuming the vapor as fast as it rises by comminglin g with the same, thus preventing condensation.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, s

'lhe float or disk B, constructed with gaschamber O and flexible pipe or pipes G H, in combination with a reservoir for containing the carbureting liquid, arranged and operating substantially as described. JOSHUA GRAY.
